Question

我试图在我的aspx页面中调用jquery函数，但它一直给我错误信息。我尝试了逐步调试，但仍然无法弄清楚任何事情。请有人告诉我可能是什么问题。谢谢。我一直收到失败回复“'处理您的请求时出现问题'

请你改变这一行：

 data: { name: 'hello' },

到此：

 data: "{ 'name' : 'hello' }",

如果仍然出错，你可以发送吗？如果你想知道究竟发生了什么，请改变这一行：

error: function (result) {
                    alert('There is a problem processing your request');
                }

到

error: function (result) {
                    alert(result.responseText);
                }

然后发送它的错误。
